Iris Identification System Using Tree-Structured Wavelet Algorithm.
Tati Rajab Mengko, Antari Ardianti, Ani Setyorini · 2000
The unique iris structures motivate the development of an automatic identification system based on iris characteristic. Texture analysis with multichannel filtering approach is meant to extract feature from iris texture images and encode them into a compact and unique information for each iris. One of the tools that can analyze texture image in multiresolution approach is wavelet transform. In this research, we propose a multiresolution approach based on a modified wavelet transform called the tree-structured wavelet transform for iris texture analysis and classitication. A MATLAB simulation program has tested texture classification algorithm on 12 texture images (taken from Brodatz texture album) and 11 iris images (including real iris image).
